Answer:
(22, 23)
Step-by-step explanation:
x + ( x + 1) = 45
2x + 1 = 45
2x = 45 - 1
2x = 44
x = 44 ÷ 2
x = 22

<span>The flagpole stands vertically on the ground. If a line is drawn from the top of the flagpole to the shadow, it forms a right-angled triangle.
Similarly, if a line is drawn from the top of the student's head to the tip of this shadow a right-angled triangle is formed.
Since it is given that the measures of both the shadows are taken at the same time and location, the angle of depression in both the cases is equal.
Therefore, by AA similarity,
height of the flagpole/ height of the student =length of shadow of the flagpole/length of shadow of the student
flagpole height/1.6m = 8.5 m/2.0m
flagpole height = (8.5 m x 1.6m )/2.0 m
=6.8m</span>
Answer:
(1, -16)
Step-by-step explanation:
<u>Vertex form</u> of a quadratic equation:
where:
- (h, k) is the vertex
- a is some constant
Given equation:
To convert the given quadratic equation to vertex form, <u>complete the square</u>.
Add 15 to both sides:
Add the square of half the coefficient of the 
term to both sides:
Factor the left side:
Subtract 16 from both sides:
Comparing with the vertex form:
Therefore, the vertex of the given quadratic is (1, -16)
